Spectral energy distributions of type 1 AGN in XMM-COSMOS. II. Shape evolution. (2014)

Keywords : surveys - galaxies evolution - quasars: general

Abstract:The mid-infrared-to-ultraviolet (0.1-10{mu}m) spectral energy distribution (SED) shapes of 407 X-ray-selected radio-quiet type 1 active galactic nuclei (AGN) in the wide-field 'Cosmic Evolution Survey' (COSMOS) have been studied for signs of evolution. For a sub-sample of 200 radio-quiet quasars with black hole mass estimates and host galaxy corrections, we studied their mean SEDs as a function of a broad range of redshift, bolometric luminosity, black hole mass and Eddington ratio, and compared them with the Elvis et al. (1994ApJS...95....1E, Cat. J/ApJS/95/1, hereafter E94) type 1 AGN mean SED. We found that the mean SEDs in each bin are closely similar to each other, showing no statistical significant evidence of dependence ...(more)
